CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield
TFLD546EG is a Surface Mount
Temperature Compensated
Crystal Oscillator (TCXO).
Operating at 3.3Vdc, the
TFLD546EG5 will maintain
4.6ppm frequency tolerance
over 20 years. The TFLD546EG
is offered in a surface mount
package for automated
assembly.

PROCESS RECOMMENDATIONS
TABLE 6.0
Solder Reflow
The component solder used internal to this device has a m elting point of
221
C. The peak temperature inside the device should be less t han or
equal to 220
C for a maximum of 10 seconds
Wash
Ultrasonic cleaning is not recommended.
Note:
1) Inclusive of calibration, frequency vs. temperature stability, supply voltage change, load change,
shock and vibration, 20 years aging.
2) Oscillator output is enabled with no connection on pad 1. Output is at high impedance when
disabled.
